I used this script years ago and re-discovered it when a client wanted a calendar on their website with several options.
Installation was quick and easy, I modified my administration page with new colors and text through the admin interface.
Then I tried to modify the calendar background colors and text in the same way, by clicking on the main menu and looking for a calendar template interface.
After I selected Template Display Preferences and received a message saying "There are no display options for this template set!"
Somehow I thought I could change the look and feel of the calendar in the same type of interface that the Admin page changed.
What am I missing?
